The Need for Advanced Circuit Materials in LEO Satellites

LEO satellites have become increasingly popular due to their ability to provide global coverage, low latency, and high-speed communication services. However, these satellites face unique challenges, such as exposure to extreme temperatures, radiation, and vacuum conditions. To ensure optimal performance and longevity, the PCBs used in these satellites must be constructed using advanced circuit materials that can withstand these harsh conditions.

I-Tera? MT40: A Game-Changer in Circuit Material Technology

Isola’s I-Tera? MT40 is a game-changer in the world of circuit materials for LEO satellite applications. This low-loss, high-performance material is designed to support the fabrication of multilayer PCBs that can operate reliably in the demanding space environment. With its exceptional electrical properties, thermal stability, and mechanical strength, I-Tera? MT40 sets a new standard for circuit materials in the satellite industry.

Key Features and Benefits of I-Tera? MT40

1. Low Dielectric Constant and Loss Tangent

I-Tera? MT40 boasts a low dielectric constant (Dk) of 3.45 and a loss tangent (Df) of 0.0045 at 10 GHz, ensuring minimal signal loss and excellent signal integrity. These properties are crucial for high-frequency applications in LEO satellites, where signal loss can lead to communication disruptions and reduced performance.

2. Thermal Stability and Reliability

The circuit material exhibits excellent thermal stability, with a glass transition temperature (Tg) of 200?C and a decomposition temperature (Td) of 390?C. This ensures that the PCBs can withstand the extreme temperature fluctuations encountered in space without compromising their structural integrity or electrical performance. Additionally, I-Tera? MT40 has a low coefficient of thermal expansion (CTE), which minimizes stress on the PCB during temperature cycling.

3. Mechanical Strength and Durability

I-Tera? MT40 offers outstanding mechanical strength and durability, with a flexural strength of 700 MPa and a modulus of 20 GPa. This makes the material highly resistant to vibration and shock, which are common during satellite launches and in-orbit operations. The high mechanical strength also enables the fabrication of thinner PCBs, reducing overall weight and size, which is critical for satellite design.

4. Compatibility with Standard PCB Manufacturing Processes

One of the key advantages of I-Tera? MT40 is its compatibility with standard PCB manufacturing processes, such as drilling, routing, and plating. This allows PCB Fabricators to easily integrate the material into their existing production lines without requiring significant process modifications or investments in new equipment.
